A vote for captain would be a good way to finish off the project. Although the lucky one who gets to give this crew a forever home will no doubt immediately execute the elected captain and install one of his own choosing. And rightly so.
Alternate plan #1 could be to surrender the captaincy to Chico's pledge "Captain Salty Balls," who already has the name for it and presumably the stones to pull it off.
Or the captain could be a shadowy mystery figure that never appears on-table, instead issuing his orders from his flagship in orbit: the murderous pirate king Captain Axiom.
